Reduce watering significantly during the dormant winter months.
Pruning Cnidoscolus megacanthus is primarily for shaping and removing dead or damaged branches. Use clean, sharp pruning shears.
Pruning can be done lightly at any time of year, but more significant shaping is best done in late winter or early spring before new growth begins.
Propagate Cnidoscolus megacanthus from stem cuttings. Take 10-15 cm cuttings from healthy stems in spring or summer. Allow the cuttings to callus for a few days before planting in well-draining soil.
Rooting hormone can be beneficial. Keep moist and warm until established.
Repot Cnidoscolus megacanthus every 2-3 years, or when it becomes root-bound. Choose a pot that is only slightly larger than the current one. Use a well-draining potting mix.
Repotting is best done in the spring before the active growing season begins. Water lightly after repotting.
